LingoOK Privacy Policy

Updated: September 2026

LingoOK is a site for English reading, dictation, and AI Q&A. This file says what we collect, how we use it, and how you can control it.

1. What we collect

Sign-in is optional. You can read, dictate, and look up words without an account.

• Account: if you sign in with Google, we receive your name, email, and photo to identify you, store practice records, and show the leaderboard.
• Practice records: after sign-in, progress, scores, and answers from reading, dictation, exercises, and AI Q&A are stored on the server and may appear on the leaderboard.
• On this device: your English level, dictation progress, tutor history, and looked-up words stay in this browser (localStorage). They are not uploaded with your account.
• Dictionary cache: looked-up glosses are cached on our server as a shared word bank. That cache does not include your name or email.
• AI Q&A: your question and the current article or dictation sentence are sent to a model service to teach or to correct how you asked.
• Feedback: when you send feedback, we store the message, page path, and reply email. Signed-in feedback uses your account email; anonymous feedback requires an email you provide.

We do not sell personal information. We do not use advertising tracking cookies.

2. How we use it

• Provide sign-in, practice history, and the leaderboard.
• Teach words and check dictation and exercises at your level.
• Cache dictionary entries so the same word opens faster next time.
• Run and protect the site.
• Read feedback and send a response to the email attached to it.

The sign-in session uses cookies and a JWT. There is no third-party ad pixel.

3. Third parties

• Google: optional sign-in.
• Model / AI gateway: answers and question correction.
• Dictionaries: Free Dictionary API, Wiktionary, and other public data.
• Content sources: TED, VOA, BBC, NASA, Project Gutenberg, Wikipedia, and similar publishers, used only as study material.
• Resend: delivery of administrator replies to feedback, when email delivery is configured.

4. Your choices

• You can use most features without signing in.
• You can sign out at any time.
• You can clear this site’s local data in your browser (level, dictation progress, tutor history, word cache).
• Signed-in records stay on the server. To delete account-linked records, contact the site operator.
• You can ask the site operator to delete feedback and its associated email address.

5. Updates

When this policy changes, we update the month on this page and in this file. Using the site after that means you have seen the new text.
